<h5 id="GrapeCity_ActiveReports_PageReportModel_TextBox_HideDuplicates_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>This property hides duplicates within a specified group or data set. When a new group instance is encountered, 
the first item is shown. Rows on previous pages are ignored for hiding duplicates. If within a table or matrix cell, 
only the text is hidden, not the textbox itself.</p>
    <p>This property is ignored in matrix subtotals.</p>
